FRS12545.

If any of the component HnEPICS_*.ini files used by h1edc to create its full channel list are modified, the CRC bit in h1edc's STATE_WORD will turn red, and its MSGDAQ will report "Modified file detected". In the same way as for real-time front end models, this indicates that a h1edc and DAQ restart is necessary to add/remove the new slow channels to the DAQ.

I wrote a bash script (h1edc_generate_daq_ini_file.bsh) which generates the H1EDC.ini file in exactly the same way h1edc does when it is started. The script runs every minute, as a controls cronjob on h1fescript0. If a modified H1EDC.ini file is generated, the original is archived and the file is updated. The h1edc model then detects the CRC change of this file and raises the CRC condition.

Attached snippet of the CDS overview shows the CRC bit (green square). Note the DAQ bit and DAQ-CRC are still blank until h1edc is added to the DAQ tomorrow.
